====== Possible research / work areas ======

Things that could be improved on from a basic system.

===== Low power design =====

Consider using: STM32L, or WL, module with lora, nrf52 or 54 if available.

===== Security =====

  * Avoiding DoS.
  * Spam / abuse.
  * Forward secrecy.
  * Key management / IDs.
  * Privacy  / anonymity / pseudanonymity. Cruisers may not always want to be trackable.

===== Mesh network protocols =====

  * Emergency messages, priority, QoS.
  * TX power management.
  * Integration also with wifi mesh, APRS, Amateur packet radio, ...
  * Use of LoraWAN where TTN or similar is available, but no other useful mesh nodes.

===== RF =====

  * Antennas, filters, and amplifiers optimised for use near masts and other radio equipment. Immunity to close VHF transmissions, and high power HF.
  * Low noise switching power supplies, e.g. for use beside VHF / AIS, HF, MF (Navtex) and even LF (Radio 4) antennas.

===== Environmental Sensors =====

  * Development of wind, air, maybe water too.
